CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application is related to and claims the benefit under 35 U.S.C. § 119(a) of Korean Patent Application No. 10-2016-0166941 filed Dec. 8, 2016, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an electronic device having a bended display and a control method therefor. More particularly, the present disclosure relates to an electronic device including a front display area and at least two separate side display areas, and a control method therefor.

BACKGROUND

Recent advances in digital technologies have enabled development of various types of electronic devices that enable users on the move to communicate and process personal information, such as mobile communication terminals, personal digital assistants (PDA), electronic schedulers, smartphones, and tablet personal computers. Electronic devices have evolved into mobile convergence devices supporting heterogeneous functions having originated from distinct fields. For example, such an electronic device may support various functions related to voice or video calls, text or multimedia messages, electronic organizers, image capture, electronic mail, broadcast reception, video playback, Internet access, electronic commerce, music playback, schedule management, social networking services (SNS), friend finder services, messengers, and dictionaries.

As electronic devices support diverse functions, various types of information are simultaneously generated. To visually represent such electrical information signals, display technologies are rapidly developing.

In recent years, there have been introduced flexible panels that use flexible substrates made of flexible materials such as plastic and are capable of maintaining display performance even when bent like a sheet of paper.

Such a flexible panel may be used to form a bended display, so that the outer edge area of an electronic device (i.e. bezel area) can be reduced and the display area can be relatively widened. This may raise the value of the product due to esthetics and utility.

A double curvature surface may be formed at the connection portion connecting separate bended displays bent in different directions. For example, the connection portion connecting a bended display bent toward the top side of the electronic device and a bended display bent toward the right side thereof may have a double curvature surface of negative Gaussian curvature given by the product of two principal curvatures.

DETAILED DESCRIPTION

FIGS. 1 through 20, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged electronic device.

Hereinafter, various embodiments of the present specification will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

As used herein, the expression “have”, “may have”, “include”, or “may include” refers to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and does not exclude one or more additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used in the present disclosure are only used to describe specific embodiments, and are not intended to limit the present disclosure. As used herein, singular forms may include plural forms as well unless the context clearly indicates otherwise. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains.

FIG. 3A shows a perspective view of the electronic device 300. In various embodiments, the electronic device 300 may include various electronic components and a housing for protecting them. The housing may include a front side, a rear side facing the front side, and lateral sides (e.g. top side, bottom side, left side, and right side) surrounding the space formed between the front side and the rear side to form the appearance of the electronic device 300. At least a portion of the housing may be composed of a display. For example, the front side and/or lateral sides of the electronic device 300 may be enclosed by displays, or the front side, lateral sides and rear side of the electronic device 300 may be enclosed by displays.

In various embodiments, the display may include a display area and a non-display area. The display area indicates an area of the display for actually displaying an image, and the non-display area 360 indicates an area of the display excluding the display area. The non-display area 360 may be used to mount, for example, various driving circuits, antennas or coils, and external interfaces for connecting to external circuits or external electronic devices. In one embodiment, the non-display area 360 may further include an opaque mechanism for distinguishing it from the display area.

FIG. 3B shows a front view of the electronic device 300. In various embodiments, the front and lateral sides of the electronic device 300 may be enclosed by displays. The lateral sides of the electronic device 300 may be enclosed by bended displays, which are bendable to have a given curvature. For example, when the electronic device 300 is viewed from the front, at least a part of the side display area can be seen as well as the front display area. Although not shown, when the electronic device 300 is viewed from the back, at least a portion of the side display area as well as the rear of the electronic device 300 can be seen due to the curvature of the side display area.

With reference to FIG. 3B, the electronic device 300 may include a front display area 310 having four sides. A bended display may be physically connected to at least one of the four sides of the front display area 310 so as to extend in the lateral direction of the electronic device in a bent form. The bended displays connected respectively to the individual sides may be divided into a top-side display area 320, a bottom-side display area 340, a left-side display area 330, and a right-side display area 350 with respect to the front of the electronic device 300. The side display areas may operate independently and may display different screens. For example, while the front display area 310 displays specific content, at least one side display area may display an icon capable of executing an application. At the same time, another at least one side display area may display a control button for controlling the content displayed in the front display area 310. At the same time, another at least one side display area may display a toolbar for a particular situation. At the same time, another at least one side display area may display a notification for a received message, call or latest news.

FIGS. 3C and 3D show a side view of the electronic device 300. With reference to FIG. 3C, the top-side display area may be composed of a bended display, which is bendable to have a given curvature. Although the entire top side of the electronic device 300 is shown in FIG. 3C as being covered with the top-side display area, only a part of the top side may be covered with a banded display and the remaining part thereof may be filled with specific mechanisms (the same applies to the bottom-side display).

In various embodiments, the side display areas, which are bent in different directions, may be physically connected through the non-display areas 360. For example, the non-display area 360 between the left-side display area 330 and the top-side display area 320 has a double curvature and is curved in two directions to form a corner portion of the electronic device 300 by physically connecting the two side display areas.

With reference to FIG. 3D, like the top-side display area 320, the right-side display area 350 may be composed of a bended display, which is bendable to have a given curvature. Similarly to the top-side display area 320, the right-side display area 350 may be configured to fully or partially cover the right side of the electronic device 300 (the same applies to the left-side display). That is, some of the side display areas may be configured to fully cover their corresponding sides, and the remaining side display areas may be configured to partially cover their corresponding sides.

FIG. 3E illustrates a side display area including external interfaces. The external interfaces 370 may be an external path of an electronic component (e.g. speaker (receiver), microphone, camera, or sensor) included in the electronic device, or a path for connecting to an external device. The external interfaces 370 may include, for example, a USB terminal, a microphone hole, a speaker hole, a key button, and an earphone interface. To accommodate the external interface 370, at least a portion of the side display area corresponding to the external interface 370 may be cut. Although FIG. 3E shows only external interfaces 370 included in one side display area, the front display area may also include external interfaces similarly to the side display area.

In various embodiments, the display area including an external interface may operate in the same way as the display area not including an external interface. For example, content can be displayed and a touch can be detected and recognized as an input in the same manner.

FIG. 4 illustrates the structure of a display according to various embodiments.

In various embodiments, the display may include a transparent window 410, a three-dimensional film 420, and a flexible panel 430.

The transparent window 410 may be configured to enclose, for example, the front and at least some of the lateral sides of the housing of the electronic device. The transparent window 410 may protect electronic components inside the electronic device by dispersing or absorbing the pressure applied from the inside and the outside. The transparent window 410 may be made of a transparent material (e.g. glass or plastic) so that the electrical information signal displayed on the flexible panel 430 can be recognized from the outside.

The three-dimensional film 420 may have a three-dimensional shape corresponding to, for example, the shape of the transparent window 410. The three-dimensional film 420 may be fabricated by molding a flat film into a shape corresponding to the transparent window 410, to which the three-dimensional film 420 will be laminated. The three-dimensional film 420 may be made of a plastic transparent film that is excellent in impact resistance and light in weight. The three-dimensional film 420 may be made of a thermoplastic polymer resin such as polycarbonate (PC), polyimide (PI), polyethersulfone (PES), polyarylate (PAR), polyethylene naphthalate (PEN), polyethylene terephthalate (PET) or cycloolefin copolymer, or a thermosetting polymer resin such as epoxy or unsaturated polyester.

The three-dimensional film 420 may be divided into a display area and a non-display area. For example, the portion of the three-dimensional film 420 corresponding to the flexible panel 430 (e.g. display area) may be substantially transparent, and the portion corresponding to the non-display area may be at least opaque. However, the entire three-dimensional film 420 may be transparent.

The flexible panel 430 may include, for example, a flat display device to maintain a flat shape. The flat display device may include a liquid crystal display device (LCD), plasma display panel device (PDP), field emission display device (FED), electro luminescence display device (ELD), electro-wetting display device (EWD), or organic light emitting display device (OLED). In particular, such a flat display device may include a flexible substrate made of a flexible material such as plastic. The flexible panel 430 may include a front display area and at least two separate side display areas in accordance with the electronic device having a double curvature surface.

FIG. 5 is a flowchart of a method for manufacturing a display according to various embodiments.

With reference to FIG. 5, at operation 510, a flat film may be molded into a three-dimensional film in accordance with the shape of the transparent window.

FIG. 6 illustrates a thermoforming process that shapes a flat film into a three-dimensional film according to various embodiments.

When the flat film is directly laminated on the transparent window having a double curvature surface, there may be a problem that a part of the flat film is lifted or bubbles are generated. Hence, the flat film needs to be shaped into a three-dimensional film corresponding to the shape of the transparent window having a double curvature surface. A thermoforming or vacuum forming technique can be used to shape a flat film into a three-dimensional film. Thermoforming is used in FIG. 6.

With reference to FIG. 6, at step (a), a flat film 630 prepared in advance may be located between the upper mold 610 and the lower mold 620. In one embodiment, the flat film 630 may be sufficiently preheated before step (a) so as to prevent ripping and folding due to the compression of the mold. At step (b), the upper mold 610 and the lower mold 620 can be compressed to shape the flat film 630. During this time, sufficient heat can be supplied to allow the flat film 630 to be freely deformed. At step (c), the upper mold 610 and the lower mold 620 may be released for decompression to obtain a film having a fixed three-dimensional shape.

With reference back to FIG. 5, at operation 520, the molded three-dimensional film may be laminated on the transparent window.

FIG. 7 illustrates a process of laminating a three-dimensional film on a transparent window according to various embodiments.

With reference to FIG. 7, at step (a), the transparent window 740 may be positioned at the upper mold 710 and the molded three-dimensional film 730 may be positioned at the lower silicone pad 720. At step (b), the upper mold 710 and the lower silicone pad 720 may be compressed so that the molded three-dimensional film 730 is completely laminated on the transparent window 740. The lower silicone pad 720 fills the empty space when the upper mold 710 is compressed, assisting in complete lamination between the transparent window 740 and the three-dimensional film 730.

With reference back to FIG. 5, at operation 530, the flexible panel may be laminated on the transparent window in which the three-dimensional film is laminated.

FIG. 8 illustrates a process of laminating a flexible panel on a transparent window in which a three-dimensional film is laminated according to various embodiments.

With reference to FIG. 8, at step (a), the transparent window 840 in which the three-dimensional film 830 is laminated may be positioned at the upper mold 810 and the flexible panel 850 may be positioned at the lower silicone pad 820. At step (b), the upper mold 810 and the lower silicone pad 820 may be compressed so that the flexible panel 850 is laminated on the transparent window 840 in which the three-dimensional film 830 is laminated. As in the case of FIG. 7, the lower silicone pad 820 fills the empty space when the upper mold 810 is compressed, assisting in complete lamination between the transparent window 840, the three-dimensional film 830, and the flexible panel 850.

FIG. 9 illustrates a flexible panel in a wide quad high definition (WQHD) environment according to various embodiments.

As shown in part (a) of FIG. 9, a flexible panel in the WQHD environment may be fabricated based on the standard resolution (2560*1440). The flexible panel may have a substantially rectangular front display area 910. To manufacture an electronic device having a front display area with curved corners, the front display area 910 having a substantially rectangular shape may be extended by a given length (e.g. 100 pixels) in directions perpendicular to the sides thereof. By processing the adjacent edges of each side extended in the vertical direction in a smoothly curved shape, it is possible to manufacture a flexible panel including the front display area 910 based on the standard resolution (2560*1440). The flexible panel thus manufactured may include at least one side display area extended from each side. For example, the flexible panel may include at least one of the top-side display area 920, the bottom-side display area 940, the left-side display area 930, and the right-side display area 950, which are physically connected to the front display area. The side display areas may be extended by the same length (e.g. 100 pixels), and may be extended by different lengths if necessary.

As shown in part (b) of FIG. 9, to fabricate a flexible panel with curved corners based on the standard resolution (2560*1440) in the WQHD environment, at least a portion of the front display area 910′ may be removed. For example, the edges of the substantially rectangular front display area may be processed to have a given curvature, so that some portions of the display area may be removed. The flexible panel may include the front display area 910′ and at least two side display areas extended from each side of the front display area 910′. For example, the flexible panel may include at least one of the top-side display area 920′, the bottom-side display area 940′, the left-side display area 930′, and the right-side display area 950′, which are physically connected to the front display area. These side display areas are substantially the same as the side display areas described in part (a) of FIG. 9.

The flexible panel shown in part (a) or (b) of FIG. 9 may be driven by one display driver chip (DDI) 970 or 970′ through an interface 960 or 960′. For example, the front display area 910 or 910′, the top-side display area 920 or 920′, the bottom-side display area 940 or 940′, the left-side display area 930 or 930′, and the right-side display area 950 or 950′ may be driven by the same display driver chip so that they display different pieces of content independently. Although not shown, the flexible panel may be driven by at least two display driver chips, and different display areas may be controlled by different display driver chips.

FIGS. 10 to 13 illustrate an electronic device including electronic components according to various embodiments.

FIG. 10 depicts an electronic device including an electronic component 1040 (e.g. speaker (receiver), microphone, camera, and sensor) without an external interface.

The electronic device 1000 without an external interface may include, for example, a speaker (or receiver) and/or a microphone including a piezo element (piezoelectric element). A piezo element is an element that uses piezoelectric phenomena to convert electric vibrations into sound waves. The speaker and microphone including a piezo element may receive a sound signal from the outside of the electronic device 1000 and output a sound signal to the outside without use of an external interface.

The electronic device 1000 without an external interface may include a camera and/or a sensor that may receive light from the outside through a portion of, for example, the front display area 1010. Specifically, the camera and/or the sensor disposed adjacent to the display area can receive light from the outside through the display. For example, in the case of a transparent display, the transparent display may receive light from the outside. In the case of an opaque display, the pixel structure of the flexible panel and/or the structure of the touch panel may be changed so that the opaque display can receive light from the outside. As another example, a camera and/or a sensor may be configured to be directly included in the flexible panel (referred to as a panel-embedded camera). The panel-embedded camera may be formed by including image sensor pixels in at least a portion of the flexible panel. The panel-embedded camera may be configured to receive light from the outside of the electronic device 1000. These techniques are well known to those skilled in the art, and a detailed description thereof will be omitted.

As shown in FIG. 11, the display of an electronic device 1100 may include a plurality of fine holes 1150, and the electronic device 1100 may include an electronic component 1140 (e.g. speaker (receiver), microphone, camera, or sensor) at a position corresponding to the fine holes 1150. The display including the fine holes 1150 at a position corresponding to the electronic component 1140 may utilize the fine holes 1150 as an external interface. Here, a fine hole may refer to a small hole with a diameter of 0.1mm or less. As the size of a fine hole is smaller, the portion where fine holes are formed is recognized as similar to the portion where fine holes are not formed, so that the whole design can provide a sense of unity. That is, when a plurality of fine holes 1150 are formed in a region corresponding to electronic components 1140 (e.g. speaker (receiver), microphone, camera, and sensor), the electronic components 1140 may input and output a sound signal from and to the outside and receive light from the outside through the fine holes 1150. The fine holes 1150 can serve as an interface for connecting the inside and the outside of the electronic device 1100.

As shown in FIG. 12, at least one display area of an electronic device 1200 may be connected with at least another display area so that a physically separate space 1250 is included there between. For example, the side display area 1220 physically connected with the front display area 1210 may include the physically separate space 1250. The physically separate space 1250 can serve as an interface for connecting the inside and the outside of the electronic device 1200. That is, when an electronic component 1240 (e.g. speaker, camera, or sensor) is disposed close to the physically separate space 1250, the electronic component 1240 may output a sound signal to the outside or receive light from the outside through the physically separate space 1250. Hence, the speaker and/or the camera may operate smoothly.

FIG. 13 shows a display area including an external interface 1310. The external interface 1310 may be an external path of an electronic component (e.g. speaker (receiver), microphone, camera, or sensor) included in the electronic device, or a path for connecting to an external device. The external interface 1310 may include, for example, a USB terminal, a microphone hole, a speaker hole, or an earphone interface. The display area may further include a key button 1320. To accommodate the external interface 1310 or the key button 1320, at least a portion of the display area may be cut.

As shown in FIGS. 11 to 13, the display area including an external interface needs to be cut. For example, the display process may further include a step of cutting for the external interface after the steps shown in FIG. 5. Specifically, after the flexible panel is laminated on the transparent window in which the three-dimensional film is laminated, a step of forming fine holes or a step of cutting at least a portion between physically connected display areas may be included in addition. This cut portion may be used as an external passage for an electronic component, as a passage for connecting to an external device, and as a region where a button key is to be mounted.

The methods described in FIGS. 10 to 13 may be applied in an individual and selective manner, but the methods may also be applied in an overlapping and simultaneous manner. They may be applied in various ways in consideration of the aesthetics of the electronic device and the performance of electronic components.

According to various embodiments, an electronic device may include: a front display area; at least two separate side display areas that are physically connected with at least one side of the front display area and form a convex curved surface in at least one space between the front and the rear of the electronic device; and a non-display area that physically connects at least two side display areas of the at least two separate side display areas and forms a convex double curvature surface in at least another space between the front and the rear of the electronic device, wherein the at least two physically connected side display areas are bent in directions so that an acute angle, a right angle or an obtuse angle is formed.

In one embodiment, the at least two separate side display areas may each include side display areas curved in opposite directions and side display areas curved in directions perpendicular to each other.

In one embodiment, at least one display area among the front display area and the at least two separate side display areas may include an external interface.

In one embodiment, the external interface may include at least one of a USB terminal, a microphone hole, a speaker hole, a key button, and an earphone interface.

In one embodiment, the front display area may include a plurality of fine holes in at least one space.

In one embodiment, the electronic device may include at least one of a speaker, a microphone, a camera, and a sensor at a position corresponding to the fine holes.

In one embodiment, the front display area may be connected with one of the at least two separate side display areas so that a physically separate space is included there between.

In one embodiment, the electronic device may include at least one of a speaker, a microphone, a camera, and a sensor at a position corresponding to the physically separate space.

According to various embodiments, an electronic device may include: a display; and at least one display driver chip (DDI) to drive the display, wherein the display may include a transparent window enclosing the front and at least a portion of the lateral side of the electronic device, a three-dimensional film having a shape corresponding to the shape of the transparent window, and a flexible panel including a front display area and at least two separate side display areas, and wherein at least two side display areas among the at least two separate side display areas are bent in directions so that an acute angle, a right angle or an obtuse angle is formed.

In one embodiment, the three-dimensional film may be divided into a region corresponding to a display area and a region corresponding to a non-display area and the regions are marked so that they can be visually distinguished from each other.

In one embodiment, the region of the three-dimensional film corresponding to a display area may be transparent, and the region corresponding to a non-display area may be at least opaque.

In one embodiment, the electronic device may further include at least one of a speaker, a microphone, a camera, and a sensor.

In one embodiment, the speaker or the microphone may include a piezo element that converts electric vibrations into sound waves.

In one embodiment, the camera may be included in the flexible panel.

In one embodiment, the display may include a plurality of fine holes in at least one region, and at least one of the speaker, the microphone, the camera, and the sensor may be disposed close to a position corresponding to the fine holes.

In one embodiment, the display may include a physically separate space between the front display area and one of the at least two separate side display areas, and at least one of the speaker, the microphone, the camera, and the sensor may be disposed close to a position corresponding to the physically separate space.

FIG. 14 is a flowchart of a method for controlling display areas of the electronic device according to various embodiments.

The electronic device including a front display area and at least two separate side display areas may separately control and operate the individual display areas to display different screens. For example, while the front display area displays specific content, at least one side display area may display an icon capable of executing an application. At the same time, another at least one side display area may display a control button for controlling the content displayed in the front display area. At the same time, another at least one side display area may display a toolbar for a particular situation. At the same time, another at least one side display area may display a notification for a received message, call or latest news.

With reference to FIG. 14, at operation 1410, the electronic device may receive an input for setting the display mode.

The input for setting the display mode can be received in various ways. For example, an input may be received from the user to set the display mode. An input for setting the display mode may be received based on the state of the electronic device. For example, the state of the electronic device may be identified based on a gyro sensor included in the electronic device, and an input may be automatically generated to set the display mode appropriate for the identified state. In addition, an input for setting the display mode may be received when a specific event occurs. At operation 1420, based on the received input, the electronic device may control each display area to display specific content according to the display mode.

In various embodiments, the electronic device may have a substantially rectangular front display area. For example, the length of the left side and the right side of the front display area may be larger than the length of the upper side and the lower side. Hence, content may be displayed in various ways according to the display mode by using the rectangular front display area and the at least two separate side display areas. For example, the display mode may include at least one of horizontal display mode, vertical display mode, full horizontal display mode, full vertical display mode, and stereoscopic effect mode.

FIG. 15 illustrates the horizontal display mode according to various embodiments. For an electronic device having a rectangular front display area 1510, in the horizontal display mode, the content 1520 is displayed on the screen so that the long sides among the sides of the front display area 1510 are parallel to the horizontal direction of the screen. For example, in the horizontal display mode, when the front display area 1510 has a resolution of 1440*2560, the content may be displayed using 2560 pixels in the horizontal direction and 1440 pixels in the vertical direction.

FIG. 16 illustrates the vertical display mode according to various embodiments. For an electronic device having a rectangular front display area 1610, in the vertical display mode, the content 1620 is displayed on the screen so that the long sides among the sides of the front display area 1610 are parallel to the vertical direction of the screen. For example, in the vertical display mode, when the front display area 1610 has a resolution of 1440*2560, the content may be displayed using 1440 pixels in the horizontal direction and 2560 pixels in the vertical direction.

In various embodiments, the electronic device may utilize the front display area and at least one of the side display areas physically connected with the front display area as a single display area. For example, in the horizontal display mode or vertical display mode, content may be displayed in an expanded display area obtained by extending the front display area by at least one side display area physically connected with the front display area.

FIG. 17 illustrates the full horizontal display mode according to various embodiments. In the full horizontal display mode, the front display area 1710 and at least one side display area 1720 are used as a single display area on the basis of the horizontal display mode.

With reference to FIG. 17, the electronic device including a front display area 1710 having a resolution of 1440*2560 may further include at least one side display area 1720 having a resolution of 1440*200 extended toward the top side 1721 or the bottom side 1722. Upon receiving an input for setting the full horizontal display mode, the electronic device may display the content 1730, which has been displayed in the front display area 1710 according to the horizontal display mode, in both the front display area 1710 and the at least one side display area 1720. For example, upon receiving an input for setting the full horizontal display mode, the same content may be displayed by using the front display area 1710, the top-side display area 1721, and the bottom-side display area 1722 as a single display area. For example, for the electronic device having the above resolution, one piece of content can be displayed in one display area being 2960 pixels wide and 1440 pixels high. In another embodiment, upon receiving an input for setting the full horizontal display mode, the electronic device may display the content, which has been displayed in the front display area according to the horizontal display mode, in both the front display area 1710 and the side display area (e.g. left-side display area 1723 or right-side display area 1724) extended toward the left and right of the electronic device.

FIG. 18 illustrates the full vertical display mode according to various embodiments. In the full vertical display mode, the front display area 1810 and at least one side display area 1820 are used as a single display area on the basis of the vertical display mode.

With reference to FIG. 18, the electronic device including a front display area 1810 having a resolution of 1440*2560 may further include at least one side display area 1820 having a resolution of 200*2560 extended toward the left side 1823 or the right side 1824. Upon receiving an input for setting the full vertical display mode, the electronic device may display the content 1830, which has been displayed in the front display area 1810 according to the vertical display mode, in both the front display area 1810 and the at least one side display area 1820. For example, for the electronic device having the above resolution, one piece of content can be displayed in one display area being 1840 pixels wide and 2560 pixels high. In another embodiment, upon receiving an input for setting the full vertical display mode, the electronic device may display the content, which has been displayed in the front display area according to the vertical display mode, in both the front display area and the side display area (e.g. top-side display area 1821 or right-side display area 1822) extended toward the top and bottom of the electronic device.

FIG. 19 illustrates the full display mode according to various embodiments. In the full display mode, the front display area 1910 and all the side display areas 1920 are used as a single display area.

In FIG. 19, for the full display mode, the electronic device may display the content 1930, which has been displayed in the front display area 1910, in both the front display area 1910 and all the side display areas 1920. The full display mode can be used to give various effects to the displayed content 1930. For example, when the content 1930 includes an object, the object may be displayed in the front display area 1910 and the shadow of the object may be displayed in the side display areas 1920, thereby giving a feeling of liveliness to the object. In another embodiment, the side display areas 1920 can be used to represent the stereoscopic effect or texture of an object.

FIG. 20 illustrates the stereoscopic effect mode according to various embodiments. In the stereoscopic effect mode, an object contained in the content may be displayed three-dimensionally based on, for example, the full display mode.

As shown in FIG. 20, the side display areas 2020 can be used to represent a three-dimensional effect of the object 2030. For example, when the front display area 2010 displays the object 2030 (e.g. front 2031 of the object), the side display area 2020 may display a side portion corresponding to the object 2030 (e.g. side 2023 or 2032 of the object), representing a three-dimensional effect. In this way, a sense of depth, thickness, or texture of the object 2030 can be represented. For example, the side display areas 2020 may be used to represent the texture of an object such as a tree, glass or stone, and a sense of thickness of an object such as paper or a book.

In various embodiments, when an object is displayed in the front display area, to display the side portion corresponding to the object in the side display area, the electronic device may pre-store 3D data for the object or predict the side portion of the object. Specifically, the electronic device can identify the displayed object (e.g. type, species or gender), retrieve the general shape for the identified object from a database, and display the general shape in the side display areas. For example, when an object displayed in the front display area is identified as a male person, the electronic device may apply a general shape of a male person to the object being displayed and control the side display areas to display the side portion of the object, thereby giving a three-dimensional feeling.

According to various embodiments, a method for an electronic device including a front display area and at least two separate side display areas to control the display areas may include: receiving an input for setting the display mode; and controlling each display area to display specific content according to the display mode indicated by the received input.
